TYPE-WRITING MACHINE.

.Application led October 7, 1916. Serial No. 124,260.

VTo all whom z't may concern:

Be it known that I, GEORGE A. SEin, citivzen of the United States, andresident of Ilion, in the county of Herkimer and State of New York, haveinvented certain new land useful Improvements' in Type-Writing both endsof the .carriage travel.

To the above and other'ends -which will hereinafter appear, my inventionconsists in certain features of construction and 'combinations andarrangements of parts, all of which will be full set forth herein andparticularly pointe out in the claims..

In the accompanying drawing,

Figure 1 is afragmentary left-hand side `elevation partly in section ofthe upper part of a typewriting machine having my invention embodiedtherein, only those parts beingv shown which contribute -to anunderstanding of the invention.

Fig. 2 is a front view of the left-hand end of the `platen and itssupporting means, parts being shown in section on the line m of Fig. 1.l

Fig. 3 is an end elevation, partly in section, showing the left-hand endpiece of the platen frame and my adjustabledevices, vthe section beingon the vline y y of Fig. 2 and looking in the direction of the arrows atsaid line.

Fig. 4 is an enlarged'fragmentary section on the line z z of Fig.43. l

Fig. 5 is a diagrammatic plan view on a I have shown my inventionembodied' in a machine which in some respects is similar to, and may-beidentical with, the No. 10

Remington typewriter, but which in other Specification of LettersPatent.

respects is different from that machine. The machine shown in thedrawing comprises a top plate 1, which below the platen 2, is depressedinto .a trough-like form as in the No. 10 Remington. Said platen has anaXle 3 which is mounted by means presently to be ,described in a platenframe, of which only the left-hand end piece 4 is shown in the drawing.Said platen frame may be mounted with provision for an up anddowrcaseshift motion in a carriage truck, which truck is not shown in thedrawing but which may be identical with that of the No. 10 Remingtonmachine. Said Remington truck comprises a rectangular "frame, the frontand rear bars ofwhich are lin the nature of grooved rails, which throughroller bearings coperate with stationary railsmounted on 4,

the top plate 1. All of this mechanism, in-v differs from that of theRemington No. 10y

m chine, however, the :type bars 5 being guided in a Series ofradialslots 6 in a. type bar segment 7 and all of saidtype bars pivotedon a curved wire 8 suitably seated in a, curved groove in the -rearface.V of 'said segment.l Said segment is secured in :any suitable -wayto brackets 10 of the top plate 1. Each 'of saidtype bars hasa slot11 inwhich plays a pin 12 projecting from a'ke'y oper- 'ated sub-lever 13,the jwhole construction being such that whenakey is depressed said pin12 moves toward the front yof the machine and throws the type bar fromits ynormal horizontal position up 'to its printing position shown inFig. 1. One or the other of the two types l4`will strike against thefront face of the platen depending ton the case position of ,the platen.A center-guide 15 for the type bars is mounted onthe segment 7 On thefront face of said-- segment, as in some prior machines, there is ananvil 16 formed on acurve in a vertical plane and against which eachtype bar strikes at about the instant of printing. It is always desir-\able vto have the two ends of the platen bear at all times the samerelationvto the typesl by the anvil 16. For this purpose I have so thata wrench can be used on it.

provided a plate 17 which is secured to they inner face of the end piece4. The axle 3.

passes through a sleeve 18, part of which is exteriorly screw threaded,and the plate 17 has a hole which is correspondingly internally threadedand the sleeve 18 is screwed into said plate. Said sleeve has anenlarged part 20 forming a shoulder which is screwed up tight againstthe plate 17, said enlarged part as here shown being formed polygonal Acheck nut 21 is valso screwed on to the threaded part of the sleeve 18tight against the lefthand tace ot the plate 17 so that the sleeve 18 isrigidly secured to said plate 17.l The end piece 4 is madewith a hole 22large enough to admit the nut 2l with provision for more or less motionof said'nut in a front and back direction. In other words, the hole islarger than the nut. rllhe plate 17 is secured to the end piece 4 bymeans of two screws 23 and 24, the one located in the 'vertical plane ofthe platen axis, in this instance directly below said axis, and theother preferably directly above said axis. @ne of said screws, forexample, the screw 23, passes through a round hole in the plate 17 andis screwed into the piece 4; but the other screw 24 passes through aslot 2 5 in the plate 17 which slot may be 'formed on a curve concentricwith the screw 23. Another slot 26 is formed in the plate 17 and iselongated in a direction toward and away :from the screw 23. A screw 27with an elongated head eccentric to the shank or threaded partof thescrew, passes through the slot 26 and is screwed into the piece 4, lthehead of said screw 27 being of a diameter corresponding to the width ofthe slot 26..

1n adjusting the machine the carriage may `be moved to its extremeleft-hand position and a gage is set against the front face of theright-hand portion of the platen which at that time will be at theprinting point.'

The carriage may then be moved to its extreme right-hand position and,the screws 23 and 24 being in place but not tightened,

the screw 27 is turned one way or the other, the turning of said screwon account of the eccentricity of its head rocking the plate 17 one wayor the other' about the screw 23 .as a center. As said screw 23 isdirectly-beneath the platen axle, turning the screw 27 will eEec-t aline adjustment of the lett-hand end of the platen toward the iront orback ot the machine. By this means' the left-hand end of the platen isadjusted exactly to the gage which has previously been set to theriUht-hand end of said platen. When the let-hand end of the platen hasbeen thus accurately adjusted it is secured in adjusted position bytightening the screws 23 and 24. When this has been done both ends ofthe platen and therefore, of course, all parts of the platen will be setin exactly the same lrelation to the type bars when any of said bars isin contact with the anvil 16.L

1t will be perceived that the etti'ect of the adjustment described is toset the front or printing face of the platen in exact parallelism withthe carriage rails, or parallel with the direction of carriage travel.

While in practice have found it necessary to employ only one set of theadjusting devices, it` will be understood that two such sets may beused, one setLat each end of the platen. 'Agaim though I have applied mynovel adjusting devices at theleft-hand end of the platen, it will beunderstood that in some makes of machines it may be desirable ornecessary to apply said adjusting devices at the right-hand end of theplaten.

The character of the adjustment provided by my novel means., isdiagrammatically illustrated in Fig. 5, where, the broken line 28, drawnthrough the front face of the right-hand end of the platen parallel withthe direction ot carriage travel, represents the correct position of thesaid front tace or writing line. 1f the left-hand end of the platen isfound to be vforward of or behind this line, it can be adjusted towardthe back or front until it is brought exactly ,to said line 28. ln thisgure of the drawing the left end of the platen is shown, in anexaggerated way, behind its proper position, and is to be adjustedtoward the front.

1n the drawing the invention is shown applied to a trontstrilre machine,and in such case the adjustmenty is in a frontiand back direction; butin a machine in which the types strike at some different angle, as in atop strike machine, for example, the adjustment would be in acorrespondingly different direction. 1n some of the claims l havereferred to the adjustment as being in printing point direction, meaningin lthe direction of the radius of the platen at the printing point.

lt will be noted that the platenl axle has a long bearing 1n the sleeve18, that said platen frame.

ture asv itAwould have been if the adjustment had not been provided. j

Various changes/can be made in the details of constructionandarrangement without departing from my invention.
